Question

How do you find the radius if you know the area of the circle?

Answer 1

sqrt(A /pi ) = r

Explanation:

Answer 2

sqrt(A /pi ) = r

Explanation:

The area of a circle is given by

A = pi r^2

Divide each side by pi

A / pi = r^2

Take the square root of each side

sqrt(A /pi ) = sqrt(r^2)

sqrt(A /pi ) = r
